The portion of the side frame 11 where the antenna radiator 2 is not disposed has a thickness-reduced region that is recessed from the inside toward the outside, the thickness-reduced region being opposite to the side rib 12. That is, a part of the side frame 11 may be used as an antenna radiation branch, and the other part is not used as a radiation branch, and the part that is not used as a radiation branch is located after the thickness is reduced.

It should be noted that the electrical connector 3 mentioned in the present disclosure may be any suitable flexible electrical connection component in an electronic device, such as cable wire (signal wire), FPC, etc.

Through the technical scheme, the first gap 40 for accommodating the electric connecting piece 3 is arranged between the side rib plate 12 and the side frame 11, so that the electric connecting piece 3 can complete side wiring, meanwhile, the part, not provided with the antenna radiator 2, of the side frame 11 is provided with the thickness reducing area so as to leave enough space for completing placement of the redundant part 32 of the electric connecting piece 3, during assembly in an assembly factory, wires are smoothed from the upper part and the lower part to the thickness reducing area (from the two ends of the side frame to the middle part) simultaneously during manual wire smoothing, the redundant area of the electric connecting piece 3 is flexibly adjusted under the condition of no cost increase, the distance tolerance between the assembly of the electric connecting piece 3 and the side frame 11 is reduced to the maximum extent, the consistent influence on the antenna performance is reasonably avoided, and mutual interference is reduced. Because the corner of frame sets up the antenna radiator usually, the side antenna environment can effectively be improved in the design of this disclosed center assembly, has satisfied the environmental requirement at battery compartment 101 side regional design antenna.

Further, as shown in fig. 3 to 7, the middle frame assembly may further include a position-limiting rib 13 embedded in the thickness-reduced region, and a second gap 41 not smaller than the first gap 40 may be provided between the position-limiting rib 13 and the side rib 12, wherein the second gap 41 has at least a portion with a larger lateral dimension than the first gap 40. The second gaps 41 may be formed between the limiting ribs 13 and the side rib plates 12, or the first gaps 40 are disposed at two ends of the middle frame assembly in the length direction to be connected with the external first gaps 40 (i.e., the first gaps 40 formed by the side frames 11 and the side rib plates 12), and both of the two setting manners are within the protection scope of the present disclosure. The electric connector 3 may include a straight portion 31 and a redundancy portion 32 stacked in a bent state, as shown in fig. 6, the straight portion 31 may be disposed in the first gap 40, and the second gap 41 of the electric connector 3 functions to further define the redundancy portion 32 in the second gap 41 on the basis of the thickness reduction region, thereby reducing the stacking region of the redundancy portion 32, enlarging the disposition region of the antenna radiator 2, and improving the quality of the electronic device.

It should be noted that, the first gap 40 referred to herein is a distance between the side frame 11 and the side rib 12 parallel to each other on the same side, and the second gap 41 is a distance between the limiting rib 13 and the side rib 12 in the thickness reducing region not smaller than the first gap 40, that is, there may be a first gap 40 between the limiting rib 13 and the side rib 12, and in the thickness reducing region, the distance between the limiting rib 13 and the side rib 12 is equal to the value between the side frame 11 and the side rib 12, that is, the portion may be the first gap 40. Second gaps 41 can be formed between the limiting ribs 13 and the side rib plates 12; one end of the first gap 40 and the other end of the second gap 41 can be arranged; the structure with the first gap 40 at both ends, the second gap 41 at the middle section, and the first gap 40 and the second gap 41 penetrating through each other is also within the protection scope of the present disclosure.

Further, as shown in fig. 4, the lateral dimension of the second gap 41 may gradually increase from the two ends to the middle to better engage with the first gap 40.

According to an embodiment of the present disclosure, as shown in fig. 4 to 6, the middle frame assembly may further include a limiting protrusion 42 protruding laterally from the side rib plate 12 and the limiting rib 13, wherein the limiting protrusion 42 may be disposed on one or both of the side rib plate 12 and the limiting rib 13, which is not limited in the present disclosure. The stopper protrusions 42 may be provided at positions of the first gap 40 where the stopper ribs 13 are provided, i.e., at both ends of the outside of the second gap 41, prevent the linear portion 31 of the electric connector 3 from moving laterally, and may define the redundant portion 32 in the second gap 41.

Further, as shown in fig. 4 and 5, the plurality of limiting protrusions 42 may be disposed in a staggered manner on both sides of the first gap 40, and compared to the case where the limiting protrusions 42 are disposed only on the side rib 12 or the limiting rib 13 or are disposed on the same horizontal line, the staggered manner may improve the limiting capability.

According to an embodiment of the present disclosure, as shown in fig. 1, the limiting rib 13 and the side frame 11 may be configured to be inserted in the thickness direction in a dovetail groove matching manner, so that the connection between the two is tighter and the position shifting is not easy to occur in use.

According to an embodiment of the present disclosure, as shown in fig. 1 and 3, the thickness-reduced region may be formed at a middle region of the side of the battery compartment 101, so that the antenna radiator 2 may be disposed at a non-middle region of the side of the battery compartment 101.

According to an embodiment of the present disclosure, as shown in fig. 7, the size of the first gap 40 may be configured to be larger than the size of the electrical connector 3 in the thickness direction. This arrangement allows the electrical connector 3 to be no higher than the upper surface of the first gap 40 so that the electrical connector 3 does not interfere with other components in the electronic device.

According to an embodiment of the present disclosure, as shown in fig. 3, a side key mounting part 5 may be further provided at one side of the middle frame assembly, and a first gap 40 is provided at an opposite side of the side key mounting part 5, so that the electrical connector 3 is routed from the other side without colliding with the side key mounting part 5.

According to a second aspect of the present disclosure, as shown in fig. 2 and 6, a middle frame support may be provided, and may include a bottom plate 10, and a side rib 12 and a limiting rib 13 provided on the bottom plate 10, wherein the side rib 12 may be provided inside a side edge of the bottom plate 10 and used for limiting a battery compartment 101, the limiting rib 13 may be provided on the bottom plate and located outside the side rib 12, and a wiring groove for accommodating the side rib 3 may be formed between the side rib 12 and the limiting rib electrical connection piece 13. Wherein the lateral dimensions of the raceway increase gradually from both ends to the middle at least partially to accommodate the redundant portion 32 of the electrical connector 3 in the raceway. Compared with the middle frame assembly described above, the middle frame bracket can accommodate the redundant portion 32 only by the side rib plate 12 and the limiting rib 13 without the side frame 11, can accommodate the electric connecting piece 3 by forming a gap at the side edge of the middle frame, can separately provide a bracket at the side edge of the middle frame to accommodate the electric connecting piece 3, and has the function of keeping the redundant portion 32 of the electric connecting piece 3 in the gap between the side rib plate 12 and the limiting rib 13 so as to prevent the redundant portion 32 from interfering with the antenna radiator 2. In the middle frame bracket, the stopper rib 13 may be detachable from the entire middle frame bracket, so that the placement position of the redundant portion 32 can be easily replaced or changed.

According to the third aspect of the present disclosure, there may also be provided an electronic device which may include the above-mentioned middle frame assembly and the electrical connector 3 provided in the first gap 40, or the electronic device may also include the above-mentioned middle frame bracket and the electrical connector 3 provided in the wiring duct. The electronic equipment has all the advantages of the middle frame assembly or the middle frame support, and the description is omitted here.

Further, as shown in fig. 7, the number of the electrical connectors 3 may be plural, arranged side by side in the thickness direction of the electronic apparatus. Taking the cross section of the electric connecting piece 3 as an example, the depth of the first gap 40 can be larger than the sum of the diameters of the electric connecting pieces 3 according to requirements, the specific size is determined according to the specific placement number of the electric connecting pieces 3, so that the electric connecting pieces 3 can be arranged in the first gap 40 side by side in the thickness direction, and the uppermost electric connecting piece 3 is not higher than the upper surface of the first gap 40, so that the electric connecting piece 3 does not influence other components in the electronic device.
